The social worker, 25, and teacher Kai Fagan, also 25, won Love Island‘s winter edition at the start of the year.
The pair have now jetted off to Mauritius for a lavish beach holiday and Sanam was eager to make the most of her down-time in the mint coloured two-piece.
She flashed her honed figure as she stretched back on a lounger, shading her face with her hands.
Sanam closed her eyes as she soaked up the sunshine yet admitted to fans: “I think it’s time I invest in a sun hat.”
They were quick to react, with a cheeky Instagram follower writing: “I’m sure Kai will you be your shade.”
The TV star then replied: “Tbf I stand behind him a lot because he’s so tall, he blocks the sun for me.”
One then added: “You are Beautiful Sanam.”
A second put: “Gorgeous.”
The lovebirds only recently returned from a romantic trip to Zante.
It comes after the pair exclusively revealed their holiday Dos and Don’ts to The Sun.
Meanwhile, back on home turf, Sanam moved in with Kai in June.
They then sparked engagement rumours as Sanam flashed a ring in a recent Instagram snap.
Kai shared a picture of Sanam wearing the stunning band on her ring finger and told his followers: “A promise.”
The ring reveal came after the beauty announced her plans for two separate weddings.
